Rozos of the Adventure Flock

Flying, First Strike
When a creature you control goes on an
adventure pay {w/b}. If you do each
opponent loses 2 life and you gain 2 life.
Put a +1/+1 counter on Rozos and that creature
whenever that adventuring creature enters
the battlefield.
By the time the flock leaves, you'll wish they only
said "Nevermore"
